hier is de oplossing; maar wel in het engels:
If You Have A @live.com or @hotmail.co.uk Account:
1. If you have a @hotmail.com email address then stop here. Read the first paragraph of this article, because that’s all you need

2. Open the Mail app on your Desire
3. If you already have another email account setup then press Menu > More > New account
4. Select Other (POP3/IMAP).
5. Select Manual setup at the bottom
6. Enter the following settings:
Protocol: POP
Email address: your email address
Username: your email address again (full)
Password: your account password
POP Server: pop3.live.com
Security Type: SSL
Server Port: 995
7. Press Next and the Outgoing server settings screen will appear
If you get an error message at this point double-check all the settings above. Make sure your username is the same as your email address.
8. For the Outgoing Server Settings use the following options (bear in mind quite a few of the boxes will already be filled in for you):
Login required: Make sure it’s checked/ticked
Username: Your full email address
Password: Your Hotmail password
SMTP Server: smtp.live.com
Security Type: TLS
Server Port: 25
9. Press Next
10. Give it a meaningful Account name (this just comes up on your Accounts list – it’s not displayed on outgoing emails)
In Your name enter your actual name – this is what will appear as the “From” value on outgoing emails
11. Press Finish Setup
12. Your account is now setup. You can press Menu > More > Settings to configure options such as:
1. Disable the “Sent from my HTC” signature
2. Change how frequently your Hotmail account is checked
3. Change how you’re notified of new email
4. Loads more, just have a look yourself!
